摘要
阐述了青海省大场金矿区地质特征(包括区域背景、地层、构造、岩浆活动等);其赋存于厚度巨大的三叠纪浅海相陆源碎屑沉积岩中,金矿体受断裂构造蚀变破碎带的严格控制。探讨了金矿矿床地质特征和矿区地球物理和地球化学特征,并研究了成矿模式,分析了找矿远景。
Tthe geological characteristic,including region background,stratum,structure and magmatic activity,in Qinghai Dachang gold mine is expatiated in this paper.The gold deposit is located in very thick sedimentary rock and controlled strictly by the fracture structure zone.The earth physical and chemical characteristic in mine area and the model of deposit forming are investigated and at the last,the mine-searching prospect is analyzed too.
